Since man first crawled into a cave, crumbs (er, bone fragments from the kill, weasel fur, seeds, etc) falling on the floor have been a problem. With the advent of plastic, we modern dudes are at a distinct advantage. I propose a rather stylish dish with roughly half of an Elizabethan collar-funnel that
attaches lightly at the neck. Crumbs from food, or errant ketchups, fall onto the collar and hopefully down an attached tube and down onto the dish for easy disposal. Great for couch potatoes and their potato chips. Or the occasional couch tomato. Anybody for tomato chips?

Actually, I was thinking the dish would be somewhat reminiscent of a bong in appearance- meaning that you could pass around the plate, and people's crumbs could, I suppose, fall into a communal trough... perfect for those brownies hot from the oven.
